Longitudinal progression of retinal nonperfusion in clinically stable diabetic retinopathy

Acta Ophthalmologica, EarlyView.
Abstract Purpose To longitudinally assess and quantify changes in retinal nonperfusion (NP) in clinically stable diabetic retinopathy (DR) using ultra‐widefield fluorescein angiography (UWF‐FA) and optical coherence tomography angiography (OCTA). Methods Fifty‐one eyes from thirty‐three patients were followed for a mean of 15.9 ± 11.4 months.

Retinal capillary density in relation to diabetes duration and levels of glycaemia in young patients with type 1 diabetes

Acta Ophthalmologica, EarlyView.
Abstract Purpose To examine retinal capillary plexus characteristics and their correlation with diabetes duration and levels of glycaemia in young type 1 diabetes (T1D) patients. Methods Cross‐sectional analysis of baseline data from an observational, prospective cohort study of 69 patients with T1D aged 6–32 (mean 16) years in T1D duration subgroups ≤

Evaluation of the Safety and Therapeutic Range of Nanosecond Laser Treatment in Rabbits

Clinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Background Subthreshold, nanosecond laser therapy has potential as a treatment for age‐related macular degeneration; however, the therapeutic range and safety profile have not been fully documented. In this study, rabbits were used for a preclinical assessment of nanosecond laser treatment.

Rethinking diabetic retinopathy: Homeostatic mechanisms for retinal clearance

Diabetic Medicine, EarlyView.
In the healthy retina, balanced production and clearance of metabolic waste and fluid maintain retinal homeostasis and normal visual function. Diabetes disrupts this balance, increasing the accumulation of metabolic waste products, including advanced glycation end products (AGEs) and advanced lipoxidation end products (ALEs), while impairing waste and ...
